2 Claims.

This invention relates generally to windows, and more particularly to a window construction including a pair of similar vertically slidable sashes within channeled frame members and a horizontally swinging sash mounted within each of the slidable sashes, together with novel means for frictionally engaging the vertically sliding sashes and, frame, and other novel means for mounting the swinging sashes within the sliding sashes so that said swinging sashes may be .completely rotated to facilitate cleaning thereof.

A primary object of this invention is to provide a window construction in which the individual sashes may be easily rotated to facilitate the washing thereof, and to provide a rotatable swinging sash structure which presents uniform appearance on each side thereof, thus avoiding the necessity of reversing the swinging sashes after the washing thereof.

' Another salient object of this invention is to provide frictional means on the vertically sliding sash members, which means will avoid the necessityof provision of pulleys and cables and counterweights.

Still another object of this invention, ancillary to the first object mentioned above, is :to provide structure whereby windows may be completely and properly cleaned from the interior of the building, wherein such windows are'mounted, thus greatly lessening the danger ordinarily associated with the cleaning of windows which cannot be reversed.

Another object of this invention is to provide frictional means, mentioned above, which can be adjusted, the frictional action being achieved by the inter-action of .two separate springs and a roller member carried thereby.

' And a last object to be specifically mentioned is to provide a device of this character which is relatively inexpensive and practicable to manufacture, extremely simple and convenient to install and to use, and which will give generally efficient and durable service.

With these objects definitely in view this invention resides in certain novel features of construction, combination and arrangement of parts and portions, as will be hereinafter described in detail in the specification, particularly pointed out in the appended claims, and illustrated in the accompanying drawings which form a material part of this application, and in which:

Figure 1 is a perspective view of a window with this invention incorporated therewith;

Figure 2 is an enlarged detailed fragmentary view of an upper'lateral portion of a vertically Sliding sash, with the friction grip unit assembly recessed therein;

Figure 3 is a vertical transverse sectional view taken on the line 3-3 in Figure 2, certain portions of the figure beingshown in elevation to facilitate the illustration;

Figure 4 is a horizontal sectional view, taken on the line 4-4 in Figure 2;

Figure 5 is a horizontal sectional view, taken on the line 5-5 in Figure 6, and showing the horizontally swinging sash member of the inside vertical sliding sash being disposed in four positions;

Figure 6 is a vertical sectional view of the inner and outer vertically sliding sashes when the same are disposed opposite to each other, and showing how the horizontally swinging sash members are each provided with pivot means atone side of each sash and at thetop and bottom thereof;

-Figure"7 is anenlarged detailed fragmentary view of a portion of the horizontal rail of a swinging sash member, in elevation, and a vertical transverse sectional view of the contiguous por-' tion of thehorizontal rail of the vertically sliding sash; and

Figure 8 is a perspective view of a portion of the lower horizontal rail in a vertically sliding sash.

Similar characters of reference designate similar or identical parts and portions throughout the several views of the drawings and throughout the specification.

Referring now to the drawings in detail, it will be noted that this invention includes a window frame having a sill I0, vertical side members l2, and a top cross member I l. The vertical side members 12 are provided with a waling strip [6 and parting strips l8 and 20, thus creating channels to guide the vertical rails 22 of the vertically sliding sashes.

The horizontal rails 24 of the vertically sliding sashes are each recessed as at 26, to receive the head portions 28 of pivot bracket members 30 which are secured to the top" and lower ends of one of the vertical rails in each swinging inner sash 23. A pair of rigid straps 32, coextensive in length with the horizontal rails 24, are secured as illustrated best in Figures 7 and 8, to these horizontal rails 24, so as to extend inwardly over eral portion of a tension regulating roller 46..

This roller 46 is provided with axial pintles 48 which ride against the cam forming bends or undulations of said spring 38 on each side of the slot 44, and this roller is engaged and'actuated by a flat spring 50 which is apertured at one end and may be held in place on the vertical rail.22,,

by means of the same screw 43 as is used to hold the undulated spring 38 in place. It will be understood that the'rece'sses 52 for the assembly 3 6 15 of suflicient width and length to allow free play and movements of the springs 38 and 55 and that the roller 46 will also frictionally engage the relatively rigid strap 54 secured to the window frame l2, If preferred, the strap 54 may be recessed into the frame l2, as indicated in Figure 5.

It will be clear that the upper and lower outwardly convexed bends (see Fig. 2) are held, by

the inherent resiliency of said spring 38, in friction binding contact with the roller tracking strip 54, while the central or intervening inwardly convexed bend is spaced from said strip 54; Also, the crest of the latter bend is in close proximity to the fiat spring 50. The spring 50 urges the roller 46 through said slot 40 and the roller is therefore at all times in frictional but free travelling contact with said strip 54. Spring 50 also keeps the pintles 48 in rollable but friction tracking contact with the stated cam-forming undulations or bends. the sash, the roller 46 is caused to' travel up- If, bythe operation of wardly between the two springs 38 and'50,'it will still remain in rolling contact with strip 54.

' However, the pintles will ride up on the crest of the intermediate bend or cam, thus exerting greater pressure on spring 38. This greater force is also aided by the roller trying to wedge T itself into the restricted space between the crest of said bend and intermediate portion of said spring 50. In fact, said bend will tend to flatten outto prevent said roller from losing friction contact with said strip 54. It follows that when the sash goes up the roller 46 goes down and when'the'sash slides down the roller travels up. Therefore, assuming that one raises the sash to open the same and, looking at Fig. 2, the roller 46 will ride down a slight degree without exerting any appreciable added tension on the spring 38. When the sash is released and allowed to sink under its own weight the roller rides up, locates itself between the center bend of the spring 38 and, in conjunction with its actuating spring 50 it checks the descent and the sash is held in a set'position.

7 The horizontal and vertical rails of the vertical sliding sashes are each provided with inwardly disposed beadsor flanges 56 to act as j stops or abutments limiting the outward move- 'ment of the swinging sashes 23 within the sliding sash members.

Each of the swinging sash members 23 is provided with a pane of glass 58, and the inner edges of each of the rails of the swinging sash members are shaped, as shown at 60, to correr of elements cited in the appended claims.

spend with the formation of the retaining putty and brad construction 10 used to retain the glass in place. Since both sides of the swinging frame members have a very similar appearance, the swinging sash members need not be reversed, after the same have been washed.

Suitable latching means, generally indicated at 12, and of any suitable character, will be secured to the vertical rails 22 of the sliding sash members, to lock the swinging sash members 23 in position, it being noted that these lock members are provided on each side of the vertically sliding sash members.

The operation of this invention will be clearly understood from the foregoing description of the mechanical details thereof, taken in connection with the above recitation of the objects sought to be achieved by this invention. In recapitulation, it may be added that the frictional engagement units 36 are adjustable, since the rollers 46 may be moved into one or other of the undulations of the spring 38, the amount of frictional action being thereby adjusted. From the above, it will be obvious that a device has been provided allowing'the cleaning of windows without actual removal of the sashes, and from inside the building whereon the windows are'situated, and that a minimum of equipment is required by this invention to carry out the functions of the device.

Although there has been shown a particular embodiment of this invention, this invention is not limited to this particular embodiment but it is desired to include in the scope of this invention the construction, combination and arrangement Having described the what is claimed as new is:

1. A sliding sash embodying a frame having a rail provided with a recess, a substantially flat invention,
